The Brook Lampreys spawned early this year and although it is widely acknowledged that this occurs when the water temperature is at 10 degrees C, I observed these Lamprey at 8 degrees.
My camera is set but after this initial film was taken the activity has been curtailed - so perhaps they have finished I will monitor the riffles for the next few days.
The camera I am using has many different settings for under water filming and I still have not settled on one that works to my satisfaction, some do not focus close enough and the last one I used zooms in to close, and as the camera is under water its impossible to see if its in focus or not until played back at home.
Still I have been pleased with the results thus far - it is a rare sight indeed to see Lampreys together and of course spawning, also if you look you can see what I think are eggs.
